First biography of the genre-defying, pioneering guitarist, songwriter, hell-raiser, and ambient hero, whose album "Solid Air" is still hailed as a classic. Spanning five decades, Glasgow-bred, hard-man John Martyn's ongoing musical career has been as volatile as his hard-drinking life. He innovated a unique musical style that placed him somewhere between Clapton and Tom Waits. Maintaining a high quality of work since the 1960s, he has survived as an acclaimed cult artist with a devoted following.
